Éco-conception d'un système de mobilité comprenant véhicules tout-électriques et réseau de recharge : Une analyse multi-perspective basée sur un modèle de simulation de la mobilité longue distance

Abstract : Electric mobility is growing accordingly to the climate change and urban pollution mitigation objectives. Indeed, vehicle electrification could reduce greenhouse gas and other pollutant emissions. However, battery electric vehicles are still a tiny share of vehicle sales despite this potential because social, technological, and economic barriers limit the adoption rate. This study deals with one of them: long-distance mobility. The objective is to analyse a mobility system including vehicles, charging infrastructures, and users on a territory to develop global insights of the stakes linked to the range, charging speed, and infrastructure network density. This work was divided into three steps. A workshop with 17 participant has been organised to define the issues of long-distance mobility and the research axis for the study. Then, the current situation of electric mobility has been examined by a literature review. Finally, a simulator has been developed to simulate the vehicle fleets on a highway and compare the system performances in different use cases and diverse evolution scenarios. At the end of the project, some methodological contributions have been identified, such as considering the vehicle and behaviour diversity and assessing the environmental impacts of long-distance mobility. Furthermore, the conclusion of this study details outlooks for battery and infrastructure network dimensioning, recommendations of good practices for users, and broader suggestions about mobility. The main conclusions are the following. First, there are significant performance gaps for long-distance trips between conventional vehicles and BEVs of different ranges. BEVs also depend on charging infrastructures that are still in development. Because technological perspectives are promising but uncertain, it is essential to care about the usage of BEVs, so they become more adopted. On the one hand, reducing driving speed on the highways would reduce performances gaps. It would favour BEVs and slow down the race for high-performance batteries, but the measure's acceptance is uncertain. On the other hand, encouraging good practices during the usage and charges is an important lever to maximise the system performance. Developing intermodality and exploring the potential of systems such as dynamic charging or battery extenders are essential alternatives to developing sober and relevant BEVs, with capacities of batteries adapted to the average needs.
